Definitions
- This invention generally relates to crowd sourced wireless networks, and more specifically, to improved security in crowd sourced wireless networks.
- the shared network may be a public network or a restricted network that is accessible to, for example, customers in a store, or people in a particular location such as a hotel or airport.
- Embodiments of the invention provide a method, system and computer program product for sharing a crowd sourced wireless network, wherein a first user uses a first device to access a specified wireless network, and the first device includes an application to grant automatically access to the specified wireless network to all of a defined group of people.
- the method comprises restricting said automatic grant of access to the specified wireless network by, when one person of said group of people requests access to the specified wireless network, a network control obtaining a determined strength of a defined relationship between the first user and said one person, and granting said one person access to the specified wireless network only if the determined strength of the defined relationship meets one or more set criteria.
- the first device uploads a series of relationship strength scores to a server; and obtaining the determined strength of a defined relationship between the first user and said one person of the group of people includes the network control receiving said series of relationship strength scores from said server.
- Embodiments of the invention allow users of devices having automated crowd sourced networking features to use additional information for the purpose of determining the strength of a relationship with a contact, before sharing a wireless network with that contact.
- this additional information is used to calculate a relationship score, which is uploaded to cloud service connected to a router or wireless access point via the Internet.
- the router or access point downloads and caches a table of relationship scores which are used to evaluate requests for network access.
- Embodiments of the invention determine which of a person's social media friends should be included in an automated crowd sourced networking technology.
- Embodiments of the invention allow wireless network administrators, or end users, to set required threshold values to be met in order to give other users automated access to the wireless network.
- Embodiments of the invention provide advances to ensure that all social network connections are not viewed as equally valid.
- factors such as personal communication history, depth of shared social network, etc, are referenced.
- the richness of this relationship is deemed to be above the required threshold, the authentication is granted.
- the same examination is performed between two users, where the second user's social network invitation was accepted by the first user, although that first user did not know the second user, the examination may now determine that the relationship between the users does not meet the required threshold. Thus, the shared authentication credentials will not be provided.
- Embodiments of the invention provide a means of balancing security and convenience.
- FIG. 1 illustrates a method and system in accordance with an embodiment of the invention.
- FIG. 2 shows a relationship strength table that may be used in the method and system of FIG. 1
- FIG. 3 depicts a computer network environment that may be used in embodiments of the invention.
- This invention relates to improved security in crowd sourced wireless networks.
- crowd sourced networks in which wireless networks are shared by multiple users, have become common; and recently, systems and procedures have been developed that allow people to share their wireless networks, or wireless networks to which they are connected, with other people without requiring that these other people manually input any password to access the networks.
- the computer system of a first user may automatically grant to the computer system of the second user access to a wireless network that the first user owns, administers, or is connected to. This may be done by automatically passing authentication credentials or an authentication key from the computer system of the first user to the computer system of the second user.
- FIG. 1 illustrates a method and system 100 having controlled automated crowd sourced networking in accordance with an embodiment of the invention.
- FIG. 1 shows a user 102 , a user device 104 , a router 106 that controls access to a wireless network 110 , a cloud service 112 , relationship table 114 , and a group 116 of friends or contacts of user 102 .
- FIG. 1 also shows a group of communication devices 120 that these friends or contact may use.
- System 100 allows users of devices having an automated crowd sourced networking feature to use additional information for the purpose of determining the strength of a relationship with a contact, before sharing a wireless network with that contact.
- this additional information is used to calculate a relationship score, which is uploaded to a cloud service 112 connected to a router 106 or wireless access point via the Internet.
- the router 106 or access point downloads and caches a table 114 of relationship scores which are used to evaluate requests for network access.
- Embodiments of the invention enhance service providers' capabilities to store and process additional data points about a user so as to evaluate the strength of relationships between people. This information will be used to determine whether a relationship exceeds the threshold for sharing of WiFi authentication keys.
- social relationship strength scores are uploaded to cloud service 112
- device 104 connects to Wifi router 106 .
- router 106 queries cloud service 112 for relationship strength entries; at step 4 , the cloud service 112 sends the table 114 to router 106 ; and the router, at step 5 , adds entries to its cache.
- friends 116 of user 102 request access to network 110 via an automated crowd source networking feature. The router 106 allows this access only if the entry in the router cache is above the allowed threshold.
- Router 106 includes or is provided with the processing memory ability needed to perform the processing and data storage described herein.
- first user device 104 may be a laptop computer, a notebook computer, a cellular phone, a personal digital assistant, or other suitable mobile communication or entertainment device.
- the user device 104 is shown as a mobile computing device, although it is understood that the device 104 can be different types of devices; and for example, the first device 104 can also be a non-mobile computing device such as a server, a desktop computer, or a workstation.
- Second user devices 120 may also comprise or include a wide range of specific devices. For instance, these devices may also include a laptop computer, a notebook computer, a cellular phone, a personal digital assistant, or other suitable mobile communication or entertainment device. Second user devices can include mobile and non-mobile computing devices such as a server, a desktop computer, or a workstation.
- Wireless network 110 can span and represent a variety of specific types of networks. Satellite communication, cellular communication, Bluetooth, Infrared Data Association standard (IrDA), wireless fidelity (WiFi) and worldwide interoperability for microwave access (Wi MAX) are examples of wireless communications that can be included or used in embodiments of the invention. Further, network 110 can traverse a number of network topologies and distances. For example, network 110 can include direct connection personal area network (PAN), local area network (LAN), metropolitan area network (MAN), wide area network (WAN), or combinations thereof.
- PAN personal area network
- LAN local area network
- MAN metropolitan area network
- WAN wide area network
- the types of data may include:
- FIG. 2 shows a table 200 identifying a multitude of data types 202 and a number of devices, represented at 204 .
- This table also includes, for each of these devices, scores 206 for these data types and a relationship strength 210 determined from these scores.
- a wide range of algorithms and procedures may be used to calculate a relationship strength value.
- the system evaluates the data described above, as well as other data the crowd sourced network feature has access to, to see if a threshold of interactions is met.
- the method may take into account the following metrics:
- the system assigns point values to each of these interactions, with the sum of these point values being evaluated as the strength of the relationship.
- the system then stores this table and caches the table locally on the network router or access point.
- Embodiments of the invention also provide a method for network administrator or users to set the required threshold value to be met.
- the system allows the owner of the wireless network to set the minimum required relationship strength threshold value to be met before sharing the network key.
- the system could be configured to allow the end user to set the strength threshold. In the case that both the user and the network administrator have set conflicting relationship strength thresholds, the owner of the network (network administrator) setting would take precedence.
